One of the biggest frustrations I've ever read in my life.
It is really disappointing that you follow 276 chapters and come across a roller coaster of quality and consistency. This was the second manga I read completely and I can say that until chapter 258 I believed it to be the best I had ever read, but from then the quality and consistency just dropped, where we see the development and growth of a relationship between 2 characters (Rui and Natsuo) that has everything to become a couple but at the end of the manga all this changes without any sense or nexus throwing away the whole context and development of these characters just pushing us to the third character that little develops or is active.
In short, the greatest frustration and waste of time I have ever had in my life, and I will certainly never read any work involving Sasuga kei again, since it has betrayed the trust of many of its readers, spoiling a work that had a future. promising.
